GENERAL DESCRIPTION
AND SYSTEM OPERATION
STEREO CASSETTE AM/FM RADIO
There are three audio systems offered. The stereo digital
logic cassette AM/FM radio with electronic tape ejection
is offered in standard and deluxe models. Both models
feature RDS (radio data system) which automatically se-
lects the best station within the chain of RDS stations cur-
rently being listened to. A trunk mounted CD changer is
also available.
AUDIO SCURITY SYSTEM
The audio security system is activated whenever the audio
system circuit is disconnected from the battery. A four–
digit security code must be entered in order for the audio
system to resume functioning. The security code is
stamped on a card located in the vehicle (usually in the
glove box). The following security code entering proce-
dure must be used to deactivate the audio security sys-
tem:
1. After connecting the audio security system to the
battery, ”CODE” will flash on the display.
2. Enter the proper security number into the unit, us-
ing the preset buttons No. 1 through 8.
3. For example, if the security number is ”1234”:
a. Press the preset button No. 1. ”CODE” will
disappear and ”1 – – – ” will appear on the dis-
play.
b. Press the preset button No. 2, and ”12 – – ”
will appear.
c. Press the preset button No. 3, and ”123– ” will
appear.
d. Press the preset button No. 4, and ”1234” will
appear and flash three times.4. The audio system will function and will transfer to
the radio.
If the incorrect security number is entered into the unit,
”Err” will appear followed by ”CODE” and there will be sev-
eral audible beeps. If this happens, repeat the security en-
tering procedure beginning with Step 2.
SPEAKERS
All audio systems use eight speakers, four speakers and
four tweeters mounted in each door.
TAPE PLAYER AND CASSETTE
CARE
The head and the capstan are the two parts of the tape
player that should be cleaned. This service should be per-
formed every 100 hours of cassette operation.
To clean the head and the capstan, use a cotton swab
dipped in rubbing alcohol.
A cassette cleaning kit may also be used to clean the head
and the capstan. Follow the cleaning kit instructions to
clean the tape player.
Do not touch the tape head with magnetized tools. If the
head becomes magnetized, it will degrade cassettes
played in the player. No service is performed on the cas-
settes. The cassette manufacturer handles warranties of
the cassettes. Store cassettes away from extreme heat
and direct sunlight.
COMPACT DISC CARE
Handle discs carefully. Store the discs in protective cases
away from the sun, heat, and dust. If the surface is soiled,
dampen a clean, soft cloth in a solution of mild neutral de-
tergent and wipe the disc clean.
